Answer: I’m working <u>to save</u> up for some new music.
Denise likes <u>to get</u> her exercise by dancing.
Dave has <u>to walk</u> the dog every morning.
Explanation:
The infinitive in English expresses the meaning of the verb in a general way, without reference to any verbal tense.
As a rule in English grammar, when a verb is in infinitive it must be preceded by the particle <em>'to'</em>, for example, <em>'to play'</em>.
According to this explanation, only the following sentences contain an infinitive:
I’m working <u>to save</u> up for some new music.
Denise likes <u>to get</u> her exercise by dancing.
Dave has <u>to walk</u> the dog every morning.
The other sentences, although have the particle 'to' are not followed by a verb.
